This Prototyping Board is Designed for Raspberry Pi B+/A+ and Raspberry Pi 2 Model B, you can combine your raspberry pi with other components, modules. There are a EEPROM for you to make your HAT for Raspberry Pi.

Features:

A big prototyping area, half of which is 'breadboard' style and half of which is 'perfboard' style so you can wire up DIP chips, sensors, and the like.

Along the edges of the proto area, all the GPIO/I2C/SPI and power pins are broken out to 0.1" stips so you can easily connect to them.

On the edges of the prototyping area, all of the breakout pins are also connected to labeled 3.5mm screw-terminal blocks. This makes it easy to semi-permanently wire in sensors, LEDs, etc.

There's also a 4-block terminal block broken out to 0.1" pads for general non-GPIO wiring.

A SOIC and a TSSOP surface mount chip breakout area, for those chips that dont come in DIP format.
